We have the concept of an inline function, but I think that a similar concept could be useful for classes. An inline class could be flagged using inheritance:

class MyClass(PyccelInline):
    _1 : int
    _2 : float

All functions of such a class would be inlined and the member variables would be declared in place of the class itself.

Therefore the following code:

class MyClass(PyccelInline):
    _1 : int
    _2 : float
    def __init__(self, a : int, b : float):
        self._1 = a
        self._2 = b

c = MyClass(1, 3.0)

would be translated to:

int64_t c_1;
float c_2;
c_1 = 1;
c_2 = 3.0;

This implementation could then be used to write non-homogeneous tuples using class notation. It would also be useful for implementing the comm class in mpi4py.
